OPCUA Server not Starting / can\'t load certificate

[juma4]

Hello everybody
I moved a project from version 3.11 to 3.15.
Now my OPCUA server does not start anymore. The error message in the LogViewer is attached as a picture.

What could this be?

Thank you for your help.

Hallo,

can you please verify if the certificate file mentioned in den Logviewer error message exists.
If this ist the case verify also that the corresponding private key file also exists in the "private" directory.
Check also the permission of these files.

Do you have the obsolete file examplecrl.crl in the "crl" subdirectory?
If yes, delete it

best regards

Andreas

The certificates exist. Since the project worked in 3.11 and the problem after pulling up exists, I have now deleted the certificates and imported those from the 3.11 project. Now the OPC UA server works perfectly.

Thank you for your help
